Agladrillia nakazaense

Agladrillia nakazaense is an extinct species of sea snail, a marine gastropod mollusk in the family Drilliidae.

[citation needed] (Original description) The shell is medium to moderately inflated with rounded whorls.

The aperture is less than half the length of the shell and extends anteriorly to form a short, well-defined siphonal canal.

The sculpture consists of moderately heavy axial ribs, about 5 to 6 visible from an angle, crossed by narrow but sharp raised threads.

[2] This extinct marine species was found in Miocene or Pliocene strata on Okinawa, Japan.
